I’ve shared this before, but Space.com has an interesting story about how the upcoming Perseid Meteor shower (peak August 11-13) came to be known as “The Tears of St. Lawrence” and also some of the science behind this annual August sky show:

Laurentius, a Christian deacon, is said to have been martyred by the Romans in 258 AD on an iron outdoor stove. It was in the midst of this torture that Laurentius cried out: “I am already roasted on one side and, if thou wouldst have me well cooked, it is time to turn me on the other.”

The saint’s death was commemorated on his feast day, Aug. 10. King Phillip II of Spain built his monastery place the “Escorial,” on the plan of the holy gridiron. And the abundance of shooting stars seen annually between approximately Aug. 8 and 14 have come to be known as St. Lawrence’s “fiery tears.”

…We know today that these meteors are actually the dross of the Swift-Tuttle comet. Discovered back in 1862, this comet takes approximately 130 years to circle the Sun. With each pass, it leaves fresh debris — mostly the size of sand grains with a few peas and marbles tossed in.

Every year during mid-August, when the Earth passes close to the orbit of Swift-Tuttle, the bits and pieces ram into our atmosphere at approximately 37 miles per second (60 kps) and create bright streaks of light.

Read on for more including diagrams and viewing tips.

Ken Scott captured these Perseid meteors last August over a 2 1/2 hour period at the D.H. Day Farm in the Sleeping Bear Dunes National Lakeshore. He says that the barn is lit by rogue lightning and that this is a composite of many meteor images, where each photo is rotated around the north star so that the ‘point of origin’ of the shower can be seen better. He understands it visually but not scientifically – anyone have a simple explanation for him?

The annual Perseid Meteor Shower peaks August 11-13 and is the closest thing to a sure thing in when you’re talking meteor showers. The Perseids kick out 10+ meteors per hour at peak, and the darker your setting, the more you will see. EarthSky has detailed tips & diagrams about this summer favorite in Everything you need to know: Perseid meteor shower:

Start watching in the second week of August, when the Delta Aquarid meteor shower is rambling along steadily, reliably producing meteors each night. Then keep watching in the second week of August, when the Perseids are rising to a peak. The Perseid shower is known to rise gradually to a peak, then fall off rapidly afterwards. In early August (and even through the peak nights), you’ll see them combine with meteors from the Delta Aquarid shower. Overall, the meteors will be increasing in number from early August onward, and better yet, the moonlight will diminish until the new moon on August 14, 2015.

Don’t rule out early evenings. As a general rule, the Perseid meteors tend to be few and far between at nightfall and early evening. Yet, if fortune smiles upon you, you could catch an earthgrazer – a looooong, slow, colorful meteor traveling horizontally across the evening sky. Earthgrazer meteors are rare but most exciting and memorable, if you happen to spot one. Perseid earthgrazers can only appear at early to mid-evening, when the radiant point of the shower is close to the horizon.

As evening deepens into late night, and the meteor shower radiant climbs higher in the sky, more and more Perseid meteors streak the nighttime. The meteors don’t really start to pick up steam until after midnight, and usually don’t bombard the sky most abundantly until the wee hours before dawn. You may see 50 or so meteors per hour in a dark sky.

An open sky is essential because these meteors fly across the sky in many different directions and in front of numerous constellations. If you trace the paths of the Perseid meteors backward, you’d find they come from a point in front of the constellation Perseus. But once again, you don’t need to know Perseus or any other constellation to watch this or any meteor shower.

2014 Perseid Meteor Shower

Without question the best meteor shower of the summer in Michigan is the Perseids, EarthSky’s Everything you need to know about the Perseid Meteor Shower has (predictably) all kinds of details and diagrams to help you get the most out of this annual display. The most important thing is to start watching now as the August supermoon is full this weekend.

Every year, from around July 17 to August 24, our planet Earth crosses the orbital path of Comet Swift-Tuttle, the parent of the Perseid meteor shower. Debris from this comet litters the comet’s orbit, but we don’t really get into the thick of the comet rubble until after the first week of August. The bits and pieces from Comet Swift-Tuttle slam into the Earth’s upper atmosphere at some 210,000 kilometers (130,000 miles) per hour, lighting up the nighttime with fast-moving Perseid meteors. If our planet happens to pass through an unusually dense clump of meteoroids – comet rubble – we’ll see an elevated number of meteors.

…The swift-moving and often bright Perseid meteors frequently leave persistent trains – ionized gas trails lasting for a few moments after the meteor has already gone. Watch for these meteors to streak the nighttime in front of the age-old, lore-laden constellations from late night until dawn as we approach the second weekend in August. The Perseids should put out a few dozen meteors per hour in the wee hours of the mornings of August 11, 12 and 13.
